Best deal between these 3 bikes?

Purchasing a new bike, this will be my everyday rider (don't own a car). Will purchase a race bike in the future. Haven't contacted any of these sellers, so don't know if they're willing to negotiate. However, considering that the ads have been posted for several weeks they should be flexible.

Whichever bike fits you best and makes you happiest is the one you should get. If you're concerned about money, just buy the cheapest one. But is $200 really worth worrying about that much? Hopefully, you'll have the bike for many years.

Plan to have the bike for years and ride it everyday. 200 dollars is not a deal breaker. I've only looked at non carbon frames because I was advised not to buy used carbon. Most I'm willing to spend is about 900

Cane supporters, what makes you choose the bike other than price. Shimano over SRAM?

All three are very good choices so you can't go wrong. The Motobecane has a triple crankset though. It also has a carbon rear triangle. I don't like either those things.

SRAM Force vs Shimano Ultegra is mainly a personal preference thing (ergonomics and double-tap shifting). They are both 2nd from their respective Brand's top of the line and are very comparable in quality.

The CAAD9 is considered to be a very stiff race bike, so you may find it a bit less comfortable than the other two for longer rides.

Get the caad. Only one that was properly photographed. If the frame is in good shape also worth upgrading as you go. Can't really speak to the other two. Sounds like the Lemond has good components. My caad weights about 17lbs and many people get theirs down to 15.

OK, I've spoken to all 3 sellers. The CAAD is running a tiagra set. So it seems I'm taking 2 steps down from the other two bikes as far as components. I will test all 3, probably Wednesday. What's standard protocol when test riding a used bike? I'd like to take each one on a 5 mile spin to get a feel for them, I know many sellers would not feel comfortable with that due to all the scumbags and thieves out there.

good luck with that... last time I bought a bike off craigslist (granted it was a trek 7.2 for $200) I left my backpack with the seller, rode around the block, checked everything out, and handed him the cash afterwards. Hell, I don't think my lbs would let someone ride a bike for 5 miles and then return it without making a purchase.
The caad9 is pretty damn expensive for what it is, $800 for a tiagra (9 speed I assume) is asking for way too much, $600 would be more reasonable. even then, I'm not sure I would take it over the motobecane.

I would expect the seller to request some form of collateral (preferably non-cash). When I was selling my bike, I made the buyer leave me his driver's license. If the seller requests you leave cash, I would leave <50% of the asking price. Basically, leave an amount where if he decides to skip you're comfortable with the price of the bike. A ~15 min ride should be standard, but confirm the duration with the seller before heading out.

Look the bike over thoroughly. Check that the wheels are true with a quick spin that they don't rub the brakes. I would take it for a quick spin around the parking lot initially, then talk to the seller before heading on a longer ride. Make sure it shifts smoothly and doesn't have weird squeaks or rattles.
